Title:
DIGITAL PREDISTORTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/230819
Kind Code:
A1
Abstract:
Systems, methods and apparatus for processing signals are described. The method includes determining a predistortion signal corresponding to an input signal by processing the input signal through a multi-stage predistortion model that is based on neural network processing and generating a transmission waveform by processing the predistortion signal through transmission electronics.
